Avaya Vantage Contacts

I have installed Avaya Vantage phones and successfully integrated with the AADS.
However, I can search in the Active directory contact in the Avaya Equinox where the AADS is enabled, but not in the Avaya Vantage.
Although I'm logging in using an email address in the active directory.

I've been working on this for a very long time and couldn't solve it.
Any suggestions?
